------------------------------------
Summary: BrentSolver has no validation of convergence accuracy or
evaluated function value leading to possible non-convergence
Key: NUMBERS-210
URL: https://issues.apache.org/jira/browse/NUMBERS-210
Project: Commons Numbers
Issue Type: Bug
Components: rootfinder
Affects Versions: 1.3
Reporter: Alex Herbert
The BrentSolver does not validate that the relative, absolute or function value
accuracy are positive and finite. This can lead to use of negative or NaN
tolerance and no possible convergence.
The evaluated function value may be computed as NaN. This invalidates any
further convergence computation.
